I really think these little runs in ATP events are great for the confidence of all the men. Once the ATP tour stops looking like a significant step up, the men will start relaxing more and perhaps making a more regular impact.
I saw Fish v Dancevic and think Fish looked beatable. Dancevic certainly looked the better player for streaks of the match, especially the weird collapse from Fish in the first.
Either way its a great experience that he can just go out and enjoy. if he keeps up his net play he should push Fish I would hope
